Rivatuner is one the leading tweak Utility available for NVIDIA GeForce and ATI Radeon based videocards.

What's a graphics card tweaker without the proper tools to do so ? Exactly; Rivatuner has been updated towards version 2.06 In this release we have included a huge number of stuff to keep you busy, obviously GeForce 8800 GT & ForceWare 169.04 support is here as well.

RivaTuner is a complete powerful tweaking environment, providing you everything you may need to tune NVIDIA GPU based display adapters. The widest driver-level Direct3D / OpenGL and system tuning options, flexible profiling system allowing to make custom settings on per-application basis, both driver-level and low-level hardware access modes, unique diagnostic and real-time hardware monitoring features and exclusive power user oriented tools like built-in registry editor and patch script engine make RivaTuner's feature set absolutely unmatched. RivaTuner supports all NVIDIA display adapters starting from Riva TNT family up to the latest GeForce 8800 series and widest range of NVIDIA drivers starting from the oldest Detonator 2.08 up to the newest ForceWare drivers family.In addition to complete NVIDIA hardware support, RivaTuner also provides limited support for display adapters based upon ATI RADEON 8500 and newer ATI graphics processors. All RivaTuner's features besides driver-level tuning options are also available on supported ATI hardware.

For novice users, we have a guide to help you through Rivatuner and setup fan speeds and overclocks on your graphics card. This guide will hopefully help you understand how to use the features that Rivatuner provides.

1.RivaTuner no longer maps OSD text to Logitech keyboard LCD, now there is separate "Show in LCD" option in the data source properties window allowing you to define independent output configurations for OSD and LCD. Previously available power user oriented MapOSDToLCD regitry entry is no longer in use.
2.Previously available power user oriented LCD font size adjustment option is now also available in the data source properties.
3.New dynamic LCD re-connection mode ensures proper LCD output when LCD software is being restarted dynamically.

-Added heuristic on-die fan PWM controller detection for G92 based display adapters to provide proper low-level fan control and reference fan duty cycle monitoring for both reference desing and alternate display adapters using the fan connected to alternate on-die PWM controller (e.g. Palit GeForce 9800GT series).
-Improved detection algorithms for core and memory clock frequency generators switching to PCIE bus clock on NV40 and newer NVIDIA graphics processors. The algorithms are still experimental, so both core and memory clock frequency generator bypassing detection can be forcibly disabled via EnableNVPLLBypassingDetection and EnableMPLLBypassingDetection registry entries.
-Updated RivaTunerStatisticsServer v3.1.1 bundled utility. This version is a maintenance release, it doesn't contain new features besides the fix mentioned above.
-Updated D3DOverrider v2.0.1 bundled utility. This version is a maintenance release, it doesn't contain new features besides the fix mentioned above.
